RADIATOR.

Application led February This invention relates to an improved radiatorfor internal combustion engines, be-

ing more particularly designed for use in connection with the engines ofmotor vehicles, and seeks7 among other objects, to

' plates will be assembled iii mating front and rear units bodilremovable at the front and rear of the radiator shell, and wherein saidunits may be thus displaced without thffneoessity of removing the shellfrom the vehicle.

Andthe invention seeks to provide a radiator well adapted for :generaluse and which, in practice, will prove entirely efcient.

Other andincidental objects will appear hereinafter.

In the drawings: Figure 1 is a front elevation of my improved radiator.l y y y Figure 2 is a horizontal'sectional vview on the line 2-2 ofFigure 1, looking in the direction indicated by the arrows.

Figure 3 is al vertical section on the line 3 3 of Figure 2.

Figure 4 is a detail perspective view particularly showing a typicalplate of the front plate unit as well as atypical plate of the rearplate unit employed.

In carrying the invention into effect, I employ a shell which includes atop tank and a'A bottom tank 11 connected with each other-.by parallelside plates 12. The top tank is formed with the usual filler tube 13,closed by a screw cap 14, and entering 'said vtank at the back .thereofis an inlet 15 while from the bottom tank leads an outlet 16. Extendingbetween the top and bottoni tanks are transversely spaced rows ofvertical tubes indicated for convenience at 17, 18, 19 and 20,communicating with said tanks sotliat water entering at the inlet 15will flow intothe top tank 1.0 to thence descend through the tubes intothe bottom tank 11` when the water will flow out at the outlet 1G.Overlying the bottoni tank between the rows of tubes 17 and 1S andbetween the rows of 1s, i925. serial No. 10,071.

tubes 19 and 20, are wear plates 2l extending from front to rear of saidtank. These wear plates maybe secured to the tank in any approved mannerandare provided at their ends with downturned lugs 22 overhanging thefront and rear walls of the tank.

- I n conjunction with the tubes, I employ a pair of front and rearmating radiating plate units 23 and 24. The unit 23 is composed of aplurality of plates 25 each having side tongues 26 and a middle tongue27 between and somewhat longer than the side tongues. At the outer edgesof the side tongues the plateis formed with notches 2S while at itsouter margin the plate is foldeil over to form ka reinforcing flange '29as well as to provide a smooth surface at the outer edge. of the plate.Extending through each of the tongues 26 of the several plates arevertical parallel tie rods 30 provided at their lower ends with heads 31while at their upper ends the rodsl carry nuts 32, and surrounding therods between adjacent plates are spacing members 33. As shown in de tailin Figure 4, each of these members is preferably in the nature of acoilspring but in assembling the plates of the unit, the nuts 32 arepreferably adjusted until said springs are substantially compressed.Thus, the springs will serve to' more or less rigidly space the platesapart but enough yielda bility will remain in the springs to allow alimited movementof the plates on the rods. ln this way sufficientrigidity of the unitis attained while, at the same time, slight movementof the plates will be permitted to accommodate any excess stresses orstrains such as might be inflicted in the practical use of theradiator.4 The unit 24 is likewise composed of a plurality of plates 34,each of which is provided with short side tongues 35 and a somewhatlonger middle tongue 36. At the outer edges of the side tongues arenotches 37 like the notches 28 of the plates 25 while the outer marginsof the plates are bent'uiider to form reinforcing flanges 3S like thefianges 29. -Preferably, the freel ends of the tongues 35 are also bentunder to form like reinforcing flanges 39, and extending through tlieside tongues 35 are parallel 'vertical tie rods 40. These rods areidentical with the rods 30 and surrounding the rods 40 between theseveral plates 34 are spacing members 41 like the spacing members 33.Thus, the plates 34 are connected to form the unit 24 and are spacedapart in parallel relation by the members 41.

The plates 25 and 34 of the units 23 and 24 are of a length to beslidably received between the side plates 12 of the radiator shell.Accordingly, the units may be assembled with the shell. by first slidingthe front unit 23 into the shell at lthe front thereof, and then theunit 24 is slid into the shell at the rear thereof. As shown in Figure2, the tongues 26 and 35 of the plate units are slidably receivedbetween the rows of tubes 17 and 18 and 19 and 20, while the tongues 27and 36 are slidably received between the rows of tubes 18 and 19. Thetongues 26 overlap the tongues 35 while the tongues 27 overlap thetongues 36 and, as will be observed, the front and rear tubes of therows 17 and 20-are accommodated in the notches 28 and 37 of the platesof the units while the front and rear tubes of the rows 18 and 19 restin the `ends of the slots between the tongues of the plates for limitingthe plates in their movement into the shell, the plates, when in place,lying flush with the front and rear faces of the shell. The radiator isthus given a neat and finished appearance while the plates of the unitsare disposed in intimate relation to 'the tubes of the shell forradiating the heat communicated to the plates from said tubes. Extendingtransversely through both units between adjacent plates thereof areupper and lower pairs of clamping rods 42 securing the units togetherwithin the shell. Thus, by removing the be slid from the shell at thefront and rear thereof, the weariplates 21 being provided lto receivethe wear of the heads 31 of the tie rods of the units. As will beappreciated, after the plate units have been thus removed, free accessmay be had to the vertical tubes of the radiator for inspection orrepair.

Having thus described the invention, what I claim is:

1. A radiator including ajshell and having rows of vertical water tubes,a radiating plate unit removably. fitting in the shell and formed toaccommodate said tubes, and means securing the unit in position, saidunit including a plurality of superposed plates, tie rods extendingthrough the plates, and yieldable spacing members surrounding the rodsbetween the plates and spacing the plates apart.

2. A radiator including a shell and having rows of vertical water tubes,a radiating plate unit removably fitting in the shell and formed toaccommodate said tubes, and means securing the unit in position, saidunit including a plurality of superposed plates, tie rods extendingthrough the plates, yieldable spacing members surrounding the rodsbetween the plates and spacing the plates apart, and means adjustableupon the rods for compressing said s acing members.

In testimony whereof I a x my signature.
